If you're like me. You part cars.
But, if I had a pick-n-pull around me, You bet I'd be there a good amount of the time.
I've heard stories of people buying engines, and having 200 heads on 2.5 blocks, 885 heads on 2.7 blocks, people selling 200 heads as 885 heads, etc.
But this is the easy way to tell exactly what head your getting, without looking under the intake manifold.
The 200 head. Came on the 2.7 ETA. Crappy head. Undesireable unless intent on staying stock. From the exhaust side, look between cylinders 4 and 5. You will see a little casting mark there. It will say 2/7 ETA.
The 885 Head. Came on the SETA, and the M20B25. Desireable head. The "good" head. Flows much better than the 200. Again, from the exhaust side. Look down at the head above cylinder 2. You will see a little circle there. And on it you will see 2.5 over 2.7. Whether or not you have the extremely uncommon 7 bearing 885 will require you to pull the valve cover. But this gives you a quick idea of what they have.
Please forgive my leaky valve cover gasket. I'll get on it once it's warm.
The AMC Head. If you look on the exhaust side, you will not see the 2.7 ETA, or the 2.5/2.7 casting, instead you will see a casted circle with an indentation, much like the blocks core/freeze plugs. You can see that indentation above cylinder number 3 on the exhaust side. That is shown here in the upper left hand corner of the picture. Thanks goes out to users Fporro from here and Sunny Bimmerforums for this picture.
The 731 head. Came on the 323i from euroland and Australialand. Decent head that can be ported out to the 885 sizes. The picture below shows that you have no casting circles, or the 2.7 ETA head, rather in the center of it between the cylinder numbers 3 and 4 exhaust ports, that there is a small casted port there, which something bolts to. Thanks goes out to user RanierHooker from E30tech for this picture.
IF you find a discrepancy between your head and this information, PLEASE post it in here or PM me so I can amend it. I still would like some similar shots of the AMC and the 731 one that are similar to the pictures I took of the Eta and 885 head. One broad, and one closeup of casting marks that identify it.
